The developers at the FreeBSD Project have released the first beta for version 9.1 of the open source FreeBSD operating system. Aimed at developers and testers, the first test build of FreeBSD 9.1 was originally expected to arrive on 6 July but later fell behind schedule. In the mailing list announcement, Ken Smith, a member of the Release Engineering Team, says that the developers "hope this will be the only BETA build", noting that it will be followed by two release candidate builds.
